Where is TW-23 located?
Silk Bamboo Hollow, or TW-23 Sizhukong, is described as Lateral end of eyebrow. In practical self-care terms, start with the small hollow at the outer end of the eyebrow. Do not rely on soreness alone to find it. Tenderness can happen in overworked tissue, but tenderness is not a diagnosis and not proof that a point is correct.
Use the broad landmark first, then soften your pressure. If the point is near a joint, tendon, face, ankle, knee, or sacral area, keep contact light and avoid sharp angles. If you cannot find the point without digging, use the surrounding muscle area instead.
How to use TW-23
Place a clean finger, thumb pad, palm heel, or soft massage tool on the outer eyebrow and temple. Hold comfortable pressure for 30 to 60 seconds, breathe normally, then release slowly. The sensation should feel dull, broad, and manageable.
If the area is small or bony, use tiny circles instead of direct force. If it is a larger muscle area, use broad pressure rather than a hard point. More pressure is not better. You should be able to relax your face, shoulders, and breathing while you hold the point.
Actionable takeaway: use comfortable pressure, not pain pressure. Stop if symptoms spread, intensify, tingle, numb, weaken, or feel alarming.

What is TW-23 used for?
In traditional acupressure, TW-23 is commonly discussed for headache, eye redness, blurred vision, facial paralysis, toothache. Treat that as traditional context, not a medical promise. A pressure point page can help you locate and use the point safely, but it cannot tell you why a symptom is happening.
The most practical use is a short self-care pause when symptoms feel mild, local, and familiar. If the symptom is severe, sudden, traumatic, neurological, infectious, digestive, eye-related, pregnancy-related, or worsening, the safer next step is medical advice rather than stronger pressure.
What the evidence says
TW-23 appears in standardized point-location references, including the WHO acupuncture point location guide. That supports the naming and location framework, not a guarantee that one point changes a symptom.
For evidence, look at the larger condition area rather than this point alone. Relevant sources for this page include WHO Standard Acupuncture Point Locations in the Western Pacific Region, Acupressure for Well-Being, Acupressure for Pain and Headaches, Headaches: What You Need To Know. The careful interpretation is simple: evidence is broader than one point. Some acupressure or acupuncture-related approaches have been studied, but protocols vary and the evidence should not be stretched into a promise for TW-23.
Safety and contraindications
Do not press over broken skin, bruising, infection, swelling, recent surgery, fragile skin, or an area with reduced sensation. Avoid direct pressure on the spine, major vessels, the eyeball, the throat, unstable joints, or any point that creates nerve-like symptoms.
Stop for sharp, electric, radiating, numbing, or weakening symptoms. Also stop for dizziness, faintness, shortness of breath, chest symptoms, sudden severe headache, vision changes, fever, unexplained weight loss, new bowel or bladder changes, or symptoms after trauma.
If you are pregnant, have a bleeding disorder, neuropathy, fragile skin, advanced osteoporosis, recent surgery, or a known serious condition, ask a qualified clinician before using pressure-point routines.
Common mistakes
The most common mistake is using TW-23 as if it needs to hurt. It does not. A pressure point can feel mildly tender, but strong pain is not the goal. If the area feels sharp, electric, bruised, or irritated, reduce pressure or stop.
A second mistake is using the point as a diagnosis. Tenderness near TW-23 does not prove that a specific organ, nerve, joint, or muscle is the cause of the symptom. It only tells you that the area responded to pressure. Keep the interpretation simple and practical.
A third mistake is pressing for too long. A short hold gives you enough information. If 30 to 60 seconds does not feel useful, a longer hold is not automatically better. Let the tissue settle, then decide whether this point belongs in your routine.
How to add it to a routine
Use TW-23 after you have checked your stop signals. Then pair it with one basic habit: slower breathing, a posture change, a warm compress, a short walk, or a clinician-approved movement. That makes the point part of a practical self-care routine rather than a stand-alone promise.
If you use more than one point, start with the easiest and safest area first. Keep the whole session under five minutes. The best routine is the one that leaves you feeling settled, not the one with the most points.
Quick fit check
Use TW-23 only when the symptom feels mild, familiar, and local enough for self-care. Skip it when the symptom feels severe, new, spreading, or medically unclear.
A good response is subtle: the area feels calmer, breathing feels easier, or you notice less bracing. A poor response is also useful information. If pressure makes the area more sensitive, stop and choose a gentler option next time.
If you are unsure, make the pressure lighter and shorter; a conservative first attempt gives you cleaner feedback than a forceful one.
Fit check: the point belongs in your routine only if it feels safe, simple, and repeatable.

Frequently asked questions
Where exactly is TW-23?
TW-23 is located around the small hollow at the outer end of the eyebrow. Use the landmark first and keep pressure broad. Do not chase the most painful spot.
Can I press TW-23 by myself?
Usually yes for mild self-care, as long as you can reach the area without twisting, straining, or using hard pressure. If the position makes you tense up, use a softer tool or skip the point.
How hard should I press?
Use a level that feels comfortable and controlled. Pain is a stop signal, not a sign that the point is working.
How long should I hold it?
Use 30 to 60 seconds, then release slowly. If the area feels irritated afterward, use less pressure next time or stop using the point.
When should I not use this point?
Do not use it for severe, sudden, traumatic, spreading, neurological, fever-related, pregnancy-related, or worsening symptoms. Get medical help when symptoms are unusual or concerning.
Bottom line
TW-23 Sizhukong is a traditional pressure point that can be used as a short, gentle self-care contact around the outer eyebrow and temple. The safest method is broad pressure, short timing, and realistic expectations.
